Abstract: | The concentration dependence of the H2O spectra in solutions of tetrabutylammonium bromide Bu4NBr in methylene chloride was investigated by IR-spectroscopy. At low salt and H2O concentrations the equilibrium: Br
f
–
+HOHf Br– HOH dominates where f indicates free or not hydrogen-bonded Br– and H2O. With increasing salt content, Br– H–O–H Br– complexes are present in addition. At high salt and H2O content, including the saturated aqueous Bu4NBr solution, H-bonded cyclic dimers seem to be important.Presented at the sixth Italian meeting on Calorimetry and Thermal Analysis (AICAT) held in Naples.
